Mr Chamberlain said he hoped that the inquest - to be conducted by Coroner Elizabeth Morris in the Northern Territory, in February - would give the family closure.

And the Torana which figured so strongly in the case will be a part of that closure should the inquest finally end the painful 30-year-old story of baby Azaria.

"We will than be able to hold a memorial service in the Northern Territory," Mr Chamberlain said.

"And I will finally be able to part with the car, though only to a museum, and never to be driven again."

Mr Chamberlain said he'd spent years putting together evidence enough to submit an application to the Northern Territory government for a fourth inquest.

"I believe our case was at least a catalyst in instigating major reforms in Northern Territory law. Their legal structure is now such that there is little opportunity for mistakes or for political interference so, in a way, something good has come out of it," he said.

"The synopsis of the facts I sent to the Northern Territory's attorney general has been received and they can see the value and importance of reopening the case," Mr Chamberlain said.

"Lindy (Chamberlain) was sentenced to life in jail in 1982 but was released when we received a pardon which meant only that we were still found guilty but forgiven. The conviction was eventually quashed with key forensic evidence for the prosecution dismissed, namely a British expert mistaking paint for blood and, we were, I believe, the first in that context ever to be formally announced innocent in court.

"People no longer doubt there are sharks in (Lake Macquarie). Similarly, incidents of dingo attacks on children are now well documented," he said.

"Had our case been heard 30 years later the outcome would have been very, very different."

Mr Chamberlain has written a 500-page book revealing every detail of the case that grabbed the attention of the world.

"It's called A Heart of Stone but it is a real hot potato. I'm now looking for a publisher," he said.
